The arrival in a city full of monsters from an adventurous balloon ride over the clouds. Riley, who had to leave his life in the Mid-West when his father started a new job in San Francisco, is a girl who acts with emotions like all of us. Joy, Fear, Anger, Disgust and Sorrow… These feelings live in the main center inside Riley’s mind and give her advice in her daily life. As Riley and her emotions struggle to get used to a new life in San Francisco, a turmoil emerges in the headquarters. Although Joy is Riley’s most important feeling and tries to keep everything positive, other feelings contradict each other in adapting to a new city, home and school.
